I have now set
        max-journal-size 50M;
and restartet bind a few times. But the journal files are still GBytes.
When should Bind flush the journal into the zone file?


Also, next to the zone and journal files I do have left-over tmp files
in the style of:
-rw-r--r-- 1 bind bind 1.2G Mar 12 08:29 tmp-36Do9oUZgU
-rw-r--r-- 1 bind bind 1.2G Mar 14 12:22 tmp-6g1o7nm7lT

Is it save to delete them?

Thanks
